Embibe Experts Solutions for Chapter: Magnetic Effect of Electric Current, Exercise 1: Odisha Board-2019

The magnetic field produced at the centre of a circular coil carrying current is $0.005 \mathrm{T}$. The magnetic field will change if both the number of turns and current are doubled.

State Ampere's law. Apply it to determine the magnetic field at a point near an infinitely-long straight wire carrying a current.

The relation between weber and tesla is $1 \mathrm{W}=1 \mathrm{T}\times 1 {\mathrm{m}}^x$. The value of $x$ is _____.

State Biot and Savart law. Derive the expression for the magnetic field at any point on the axis of a circular current-carrying loop. Find its value at the centre of this loop.
